Well, you pass the written test, and then get through the dry run with the staffers, then what? It seems they may pick you because they like the way you look, or think your voice sounds good on TV, or whatever. What rules do they go by? I’ve been through the written test and the dry run four times and never got called. What’s the deal?
I think I see your problem. That should have been:
“What is the unwritten criteria for selecting Jeopardy contestants?”
It’s criterion, Finagle. 
Criteria. There can be more than one.
“What we have here is failure to communicate.” – Strother Martin, anticipating the Internet.
What is the unwritten criterion OR what are the unwritten criteria.
Get it right. :rolleyes:
There’s only one
Criterion.
Folks inferi-ah
Say, “One criteria”!
(Any idea who wrote that? I think it was Azimov.)
Stop trying to whitewash your nitpicking with those silly emoticons.
